Poly[tetra­butyl­ammonium [chlorido­hexa­methyl-μ3-sulfato-distannate(IV)]]

In the structure of the title coordination polymer, {(C16H36N)[Sn2(CH3)6Cl(SO4)]} n , the two independent Sn(IV) atoms are coordinated in a trigonal-bipyramidal manner by three methyl groups in the equatorial plane and in the axial positions by either two O atoms of bridging SO4 (2-) anions or by a Cl atom and one O atom of a bridging SO4 (2-) anion, respectively. The [Sn2(CH3)6Cl(SO4)](-) anion forms an infinite zigzag chain parallel to the c axis. The cations are situated between these chains. Two of the four butyl groups of the cation are partially disordered over two sets of sites with site occupancies of 0.79 (2):0.21 (2) and 0.75 (2):0.25 (2), respectively. Weak C-H⋯O hydrogen-bonding inter-actions help to consolidate the crystal packing.
